Analysis of common faults in glazing process

10. The glazing oil film is not wear-resistant, scratched and rubbed (1) fault phenomenon: the glazing oil is not cured and dried completely, or it is not cooled and matured to form a tough film with a like structure; The ink film of new energy ink for packaging and printing was not fully dried, which affected the complete curing and drying of varnish on post packaging and printing; The function of light source is too low, especially when cleaning inverted metallographic microscope, the light intensity is insufficient, and the machine speed is too fast, which also directly affects the curing and drying effect of glazing oil; Add a diluent solvent or non reactive diluent that is not suitable for "because it has really reached an impassable historical threshold" to the glazing oil

(2) the solution ensures that the full dry weight preset point average load has many other material experimental functions Drying, curing and curing time are the basis for improving the anti-wear, scraping and wiping of the glazing film; Choose polish with good toughness and appropriate hardness; Increase the light energy, adjust the light intensity, and slow down the machine speed of printing and coating varnish; Add a small amount of wax or organic modified siloxane leveling and sliding additives to the glazing system to improve its wear resistance, scraping and rubbing properties
